Application filed February 1; 1913. Serial No. 745,573.

To all whom it may concern:

dds it lmown that I, JOSEPH C. HARVEY, 8 citizenr'ot the United States, residing in Chicago, in the county of Cook and State lliinois, have invented certain new an usefullmprovements in Type-Writing Machines, of which the following is a specifica- Zion.

- This. invention relates principally to devices for making typewritten records, on tally strips, of entries on bills and the like.

it has been the custom in some instances to superpose a tally strip upon a bill, in

such position that the amounts appearing in the right-hand columns on the bill are also typewritten on. the tally strip. The types strike through the ribbon directly upon both the bill and the strip. The body oi'the bill shows inked typewritten impressions, while the amounts are typewritten in ink on the tally strip, and with carbon impressions in the right-hand column of the bill. This is an objection. as it is desired that the amounts on the bill should also appear in ink.

-Une of the principal features of my improvements is to provide simple, inexpensive and readily applied means, whereby the entire bill may be typewritten with ink or may show ink-ribbon impressions. while a suitable record is made upon the tally strip.

To this end, i employ a tally strip which is made oi? transparent or translucent paper, and around the platen I place a band of carbon paper with the carbon side exposed. T he tally strip is superposed upon the band,

and the bill. is superposed on the tally strip.

The type impressions are therefore made on the underside of the tally strip, but this difficulty is overcome by making the tally strip of translucent paper. so that the typewritten matter may be read by looking the figures thus appearing in their natural shape and order. p The tally strip itself is illustrated as mounted on spools, which are carried upon a frame that isattached to the sheet-positioning tablet which is commonly used upon. the'platen frame oian Underwood typewriting machine. The spools may be arranged between the ends oi the tablet, so that the tally strip maytake a record of amounts written in columns at the middle of thebill or document; but of course the spools may be placed in other positions, as

for instance, at the righthand end of the tablet,,so as to take numbers written in the right-hand. columns on the bill or worksheet. 1 I Other features and advantages will herematter appear.

. In the accompanying drawings, Figure 1 1s a perspective front'view (if the platen carriage of an Underwood typewriting'n a chine, showing my improvements applied thereto. Fig. 2 1s a diagrammatic view showing the carbon band upon the platen,

and illustrating the appearance of the reversed letters written'o'n'the underside of the tally strip. Fig. 3 is a View of carbon band for the cylindrical platen.- Fig. 4 is a side elevation to illustrate the friction-gear connection between the tallystrip spools. Fig. 5 is a sectional side elevation of the various devices.

Said Underwood machine usually comprises a cylindrical platen 1, revolubly mounted by means of an axle '2 in a platen frame 3. Feeding rolls 4 are usually provided: but in this case the rolls may (as illustrated) be omitted at the portion of the platen which is occupied by the tally strip, to avoid smutting the tally strip.

The platen is surrounded by a band 5 of carbon paper. which closely hugs the platen. and may be formed in one way by overlapping the ends of a strip as at (3 (Fig. 3), and joining the overlapping-ends in any suitable manner, as by paste or ,mucilage. This makes practically an uninterrupted band. which, if a durable carbon is used, will yield a very large number of copies. and in fact may outlast several tally strip rolls. If desired, a complete band may be pasted to the surface of the platen.

The tally strip 7, made of translucent paper. extends from a delivery spool 8 to a winding spool 9 the strip extending from one spool down to and around the platen and up to the other spool. and being carrie beneath a guide rod 10. which extends along the platen and is fixed at its ends to the platen frame It will be seen at Fig. 5 that this rod is back of the platen and beneath the spools, and that the tally strip is hence caused to grip the platen from the rear side thereof to-the top, and to extend backwardly from the top around saidguide rod 10; thus. giving the tally strip so much grip upon the; platen that the latteriwilldrive the strip;

of one form I "preferably no feed rolls4 being employed '5 is placed around the being easily at this point. i

In the operation of the machine,'the band platen. The strip may be cut the proper. length and wrapped around the platen, and its edges secured at 6 to make a complete hand. Then the tally Strip is led from delivery spool 8 and in Sorted at the rear side of the platen and carried around the same and up in front thereof and back under the rod 10, and then up to the winding spool 9. Then the bill or worksheet 11 is inserted, and its front and side edges positioned by means of the usualsheetpositioning tablet l2; and then the feeding rolls 4: are set against the platen, and the typewriting operation proceeds in the usual 4 manner, the type striking through the usual ribbon 13 against the front of the platen l or the work thereon. The bill or work-sheet 11 may extend on each side of the tally strip, as seen at Fig. 1, so that the strip will take off only the amounts that are entered down theside of that portion of the bill, butother relative arrangements or dispositions of the bill and the tally strip may be adopted. As the writing proceeds line by line, the tallystrip winds up on the spool 9, and the type-' Written impressions are made in ink on the work-sheet l1, and in corresponding-placesare made in carbon on theback of the tally strip 7, as at Fig, 2; these impressions being made in reversed or unnatural positions, but read from the front side of the tally strip, owing'to the translucent character thereof.

The delivery spool 8 is rotated by means of the pull of the revolving platen upon the tally strip 7; and a gear 1-1 connected to said spool drives a pinion 15 connected to the winding spool .9; a friction washer 16 interposed, however, between -the pinion l5 and the spool 9, so as to permit the pinion 15 to slip; said pinion being preferably of smaller diameter-than the gear ll, and the friction Washer 16 permitting the pinion 1-3 to turn con siderably faster than the winding spool, whereby the tally strip is kept taut, but without danger of breaking the strip, as there is only a light tensionthereon.

These S)O()lS are mounted a mu a -)air of brackets 17-secured by screws 18 to the -underside of the tablet l2; and the latter-may be adjusted along the rod 10, together with being and secured eithercarried on said mount; whereby said mount and spool are adjustable together with said sheetmsitioning tablet.

2. The combination with and a rotary platen mounted thereon. said frame comprising a paper shelf behind the platen, of ported on thefr ame at the delivery side of and above the platen, in position to gage the leading edge of a work-sheet extending .around the platen and. over the printing a platen frame a sheet-positioning tablet supalong the platenpoint, a mount secured to said tablet, and a "tally strip spool carried on. said mount, whereby said tablet and'spool are adjustable together lengthwise,of the platen in a single operation.

.3. The combination with aplaten frame I and a rotary'platen mounted thereon, said frame comprising a paper, shelf behind the platen, of a sheet-positioning tablet supported onthe frame at the. delivery side of and above the platen, in'position to gage the leading] edge of a work-sheet extending around the pla'ten'andv over the printing point, a mount secured to said tablet, and tally strip receiving and ried on said mount, said adjustable together along the platen to different positions along the platen.

4. A typewriter combining a platen, a sheet-positioning tablet above the platen to cooperate with a work-sheet at the delivery side of the platen, a mount secured to the tablet, and a tally strip spool carried on said mount, saiditablet an'd spool being ad justable together in a single operation along the platen in a letter-spacing direction.
